黄河三角洲高效生态经济区生态环境承载力分析

Analysis on Ecological Environment Bearing Capacity in High-efficiency Economic Zone in Yellow River Delta

以黄河三角洲19个地区2010年统计年鉴的数据为依据,应用生态足迹法,对该区2010年的生态足迹进行计算与分析。结果表明,黄河三角洲地区的生态足迹均为赤字,人均生态足迹为68.396hm2,人均实际可利用生态承载力为14.057hm2,人均生态赤字为54.339hm2。反映出评价区人类的生产、生活强度超过了生态系统的承载能力,区域生态系统处于被人类过度开发利用状态。

According to the data of the statistical yearbooks of 19 regions in the Yellow River delta in 2010, by using footprint method,ecological footprints in these areas in 2010 have been calculated.It is showed that per capita ecological footprint of the Yellow River delta area in 2010 was 68.396hm2 ,and available per capita ecological capacity was 14.057hm2 ,and per capita ecological deficit was 54.339hm2 .It shows that the human load has already stayed beyond the regional bio capacity,and the regional natural eco system has been in a state of over exploitation by human activities.
